I can't play corners !!!

Fc 26 / Laptop / I5 10500h / rtx 3060 / 32gb ram / 1tb ssd storage

Since day 1 with fc 26, as of 19 September, I haven't enjoyed the game with full, normal and optimized gameplay and experience ! I feel like I have spent my money on nothing !

I have been facing problems in the game (some of them with a lot of trials and optimization settings and trying different solutions worked better, like playing on all low settings, lowering ration and resolution,  especially after update v1.0.4, but still I haven't enjoyed a full no error experience !).

Those Problems are :

When adjusting settings on 60 fps with a even low graphics, still lags and stutters ! although my specs can run it on high or even ultra I believe !
some errors in menu in FUT especially, like hitting back button and doesn't go back to previous menu.
some modes runs ok and some with all updates till now doesn't run at all (like pro clubs, there is a huge delay and complete freeze with my players, while opponents move normally around me !). In rival for example, may lag and have delay, but in rush its normal !

Gameplay problems, like Ai defending is so weak.

THIS IS A WEIRD PROBLEM. 

whenever a corner is played, whether for me or against me, there is huge delay occurs that makes my players heavier, and opponents take advantage of this and score a goal on me through a counter attack and I  helplessly can’t defend it! also happens with penalties and free kicks too!

AND RECENTLY AFTER LATEST UPDATE 23 OCT. 

Matches get out suddenly and says connection lost and game is under review, although my connection is fine. I have lost matches I was winning in them and haven't been counted as wins !

Like I said, I am extremely disappointed in this year's fc 26 and have felt I doesn't deserve even one penny on it. haven't enjoyed the game at all. I hope you fix this soon and quickly and make things right !
